Astronomers found the source of a mysterious distant light in space

Posted by in category: space

Scientists discovered a mysterious light in what they previously believed was a darker region of space. The light, which James Webb picked up, was initially invisible when Hubble observed the area. But scientists aren’t quite sure what caused this mysterious light in space, so they’re still searching.

Brain-inspired computing system based on skyrmions ‘reads’ handwriting

Posted by in category: robotics/AI

A computing device that uses tiny magnetic swirls to process data has been trained to recognize handwritten numbers. Developed by RIKEN researchers, the device shows that miniature magnetic whirlpools could be useful for realizing low-energy computing systems inspired by the brain.

Our brains contain complex networks of neurons that transmit and process . Artificial neural networks mimic this behavior, and are particularly adept at tasks such as .

But consume a lot of power when run on conventional silicon chips. So researchers are developing alternative platforms that are specially designed for brain-inspired computing, an approach known as neuromorphic computing.

Sima, the 47 months-old Sprague Dawley rat — interview with Dr. Harold Katcher

Posted by in category: futurism

Dr. Harold Katcher, Cheif Scientific Officer of Yuvan Research Inc., is interviewed by Nicolás Cherñavsky and Nina Torres Zanvettor about the rat Sima, a Sprague Dawley rat that has lived for 47 months (exceeding the maximum lifespan of 45.5 months of this rat strain) thanks to a treatment with E5, a plasma-based therapeutic developed by Yuvan.

Anti-ageing scientists extend lifespan of oldest living lab rat

Posted by in categories: biotech/medical, food, life extension, neuroscience

The results from Katcher’s latest study will be written up when Sima dies, but data gathered so far suggests that eight rats that received placebo infusions of saline lived for 34 to 38 months, while eight that received a purified and concentrated form of blood plasma, called E5, lived for 38 to 47 months. They also had improved grip strength. Rats normally live for two to three years, though a contender for the oldest ever is a brown rat that survived on a restricted calorie diet for 4.6 years.

“The real point of our experiments is not so much to extend lifespan, but to extend youthspan, to rejuvenate people, to make their golden years really potentially golden years, instead of years of pain and decrepitude,” Katcher said. “But the fact is, if you manage to do that, you also manage to lengthen life and that’s not a bad side-effect.”

Results from such small studies are tentative at best, but some scientists believe the work, and similar efforts by others, has potential. A preliminary study from a collaboration between Katcher and experts at the University of California in Los Angeles found that infusions of young blood plasma wound back the biological clock on rat liver, blood, heart and a brain region called the hypothalamus. Commenting on the work in 2020, Prof David Sinclair, a leading expert on ageing at Harvard medical school, said if the finding held up, “rejuvenation of the body may become commonplace within our lifetimes”.

New controversial theory: Past, present, future exist simultaneously

Posted by in category: futurism

Dr. Kristie Miller, co-director of the Centre for Time at the University of Sydney, explained that the block universe theory says that our universe could be seen as a big four-dimensional block of spacetime that holds everything that ever happens.

In the world of blocks, there is no “now” or “now.” Within the three directions of space and the one direction of time, all moments only exist in relation to each other. Your experience of the present is just a reflection of where you are in the block world at the time. The “past” is just a piece of the world at a different time. The “future,” on the other hand, is at a different time.

So, is time just a trick your mind plays on you? And, more importantly, is it possible to go back in time?
